Actually we already support this if you click on the site name in the header. For reading view this is just under the menu in the upper right corner and in the editor it is right next to “PowerPoint” online in the header.

Hi, if the sender of the file granted you permission then you can download via the “…” or the File menu. If you don’t have the download option, then likely you do not have permission to download and you should contact the sender.

Thanks for the clarification. Given that PowerPoint already supports notes I’m going to decline this request. If you are looking for better notes in PPT vs. the book please contact who is providing you with the PPT.
